What side effects can happen during or right after a Remicade (infliximab) infusion?
Remicade can cause infusion-related reactions, which may start during the infusion or shortly after. These reactions can include symptoms such as fever, chills, rash, itching, hives, shortness of breath, chest pain, dizziness, or low blood pressure. In some people, a more severe reaction can occur, such as anaphylaxis or problems breathing, though this is less common.
Infusion reactions are one of the main safety concerns doctors monitor for during Remicade administration.
What short-term side effects are people most likely to notice after the infusion?
Beyond infusion reactions, short-term effects can include:
- Headache
- Fatigue
- Nausea
- Muscle aches
- Flushing or feeling unwell
If symptoms appear after leaving the infusion center, people are generally advised to contact their clinician promptly—especially if they have trouble breathing, swelling of the face or throat, widespread hives, or feel faint.
What long-term risks should patients know about (including infections)?
Remicade is an immune-modulating medicine, so one major category of risk is infection. Patients and clinicians watch for signs of infection such as fever, cough, burning with urination, skin infections, or worsening fatigue. Serious infections can occur, and people with certain risk factors may need closer monitoring.
Another important long-term concern is reactivation of infections that were previously controlled by the immune system, such as tuberculosis (TB) and hepatitis B. Because of this, clinicians typically screen for TB and hepatitis B before starting treatment.
What other serious side effects are associated with infliximab?
Serious but less common risks can include:
- Severe allergic reactions (including anaphylaxis)
- Neurologic issues (such as worsening multiple sclerosis-like symptoms)
- Liver problems (unusual fatigue, dark urine, yellow skin/eyes)
- Blood-related abnormalities (easy bruising, unusual bleeding, persistent infections)
- Certain cancers, especially with long-term immunosuppression (risk varies by individual)
What should trigger urgent medical care?
Seek urgent help if you develop signs of a severe infusion reaction or serious infection, such as:
- Trouble breathing, wheezing, or throat swelling
- Chest pain or fainting
- Rapid widespread hives or severe rash
- High fever, severe chills, or worsening symptoms of infection
How can side effects be reduced or managed during Remicade treatment?
Clinicians often reduce the chance and severity of infusion reactions by using premedications (commonly antihistamines and sometimes acetaminophen or corticosteroids) and by slowing the infusion rate for people who have reacted before.
They may also adjust treatment if a person develops significant side effects, including holding doses while infections are evaluated or stopping therapy in certain severe reaction scenarios.
Does Remicade’s “side effect profile” change if I’m also taking other medicines?
Yes. The risk of infections and other complications can rise when infliximab is combined with other immunosuppressive drugs (such as corticosteroids or other biologics). Your clinician will consider your full medication list when deciding how to monitor and whether adjustments are needed.
